Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477726, here are decompositions:

3 + 31477723 = 31477726
29 + 31477697 = 31477726
149 + 31477577 = 31477726
173 + 31477553 = 31477726
347 + 31477379 = 31477726
563 + 31477163 = 31477726
647 + 31477079 = 31477726
659 + 31477067 = 31477726

Showing the first eight; more decompositions exist.
